Abstract

The invention belongs to the technical field of consumer electronics, and particularly provides an alternating current and direct current dual-purpose teaching machine. The alternating current and direct current dual-purpose teaching machine is composed of a shell, a lithium battery, a power module, a power interface, a teaching machine control module, a horn and a signal interface; the lithium battery, the teaching machine control module and the horn are arranged inside a power shell, the power interface and the signal interface are arranged on the side face of the power shell, the lithium battery and the power module are connected with the teaching machine control module, and the teaching machine control module is connected with the horn. The alternating current and direct current dual-purpose teaching machine has the advantages that the problem that the battery in an existing alternating current and direct current dual-purpose teaching machine needs to be replaced regularly in the prior art is solved, the use is convenient, the cost is low, and energy conservation and environmental protection are possessed.

Description

technical field [0001] The invention belongs to the technical field of teaching instruments, in particular to an AC and DC dual-purpose teaching machine. Background technique [0002] At present, teaching machines have been widely used. Most of the classrooms are equipped with teaching machines. However, teaching machines generally use mains power as the power supply, but they cannot be used when there is a power failure or when there is no mains socket. The battery box is installed in the machine, but the power consumption of the teaching machine is relatively large, and the battery needs to be replaced frequently, which is also very inconvenient. Contents of the invention [0003] The purpose of the present invention is to solve the problem in the prior art that the AC / DC dual-purpose teaching machine requires frequent battery replacement. [0004] For this reason, the present invention provides a kind of AC-DC dual-purpose teaching machine, is made of housing, lithium ...
